Another Guilty Pleasure
Constructing, deconstructing, and navigating sucessively smaller iterations on fractal orbital diagrams. Generating pictures of the Mandelbrot set at ten-million magnification, and then setting the colors to flow (incredible--like Peter Max or something). Generating julia sets and cantor sets. I don't know that I learn a thing from all of this--but the pictures are incredibly beautiful and wonderful. Doesn't seem like much guilt would accrue--but let me tell you--you can spend some time with some of these--particularly if you're using hyperbolic functions.
